The Interinstitutional procedure authority table (AT) is a controlled vocabulary listing the different procedures used in the context of data exchange between the institutions involved in the legal decision-making process and the Publications Office of the European Union. It provides an authority code, the start-use date of the concept and labels in all official EU languages. The Interinstitutional procedure authority table is under governance of the Interinstitutional Metadata Maintenance Committee (IMMC) and maintained by the Publications Office of the European Union on the EU Vocabularies website.
